NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-secret package and not the libvirt-daemon-driver-secret package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt's API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).
